I '0 all whom it may concern:

Be it known that we, Roy S. NnLsoN and VVINFIELD S. NnLsoN, citizens ofthe United States, residing at Oklahoma, in the county of Oklahoma andState of Oklahoma, have invented certain new and useful Improvements inOil-Burners; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to improvements in oil burners.

The object of the present invention is to improve the construction ofoil burners and to provide a simple, practical and comparativelyinexpensive oil burner designed for use in stoves, furnaces and variousother heating devices and adapted for burning coal oil and otherhydrocarbon.

i/Vith these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion and minor details of construction may beresorted to without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawings Figure 1 is a side elevation of an oil burnerconstructed in accordance with this invention, Fig. 2 is a centralvertical sectional View of the same. Fig. 3 is a similar view taken atright angles to Fig. 2, Fig. 1 is a horizontal sectional view on theline l4c of Fig. 3, Fig. 5 is a. side elevation of the upper section ofthe burner proper. Fig. 6 is a reverse plan view of the base, Fig. 7 isa detail view of the'retort.

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

In the accompanying drawings in which is illustrated the preferredembodiment of the invention, the oil burner comprises in itsconstruction, a retort and a burner proper having a base 1 ofsubstantially cylindrical form provided at the bottom With supportinglegs or lugs 2 and having an inper section is provided at the junctureof the two portions with a shoulder 8 adapted to rest upon the upperedge of the base.

The upper section of the burner proper is also provided below thehorizontal shoulder 8 with an annular face 9 arranged vertically andfitting the interior of the base at the top thereof as clearly shown inFig. 2 of the drawings. By this construction a tight connection is madebetween the upper section and the base at the top and bottom of thelatter. The upper. section is also provided at the bottom of its loweror inner portion with an exterior annular recess 10 which forms ashoulder and which fits within the annular flange 3 of the base. Theannular flange 3 extends from the vertical walls ofthe base to thebottom of the up per section and the tapering of the latter forms 'anintervening space 11 between it and the base. The flange 3 is providedwith air inlet openings 12 which are located at the bottom of theintervening annular space 11 and the lower tapered portion of the innersection is provided with inclined perforations 13 arranged at intervalsand adapted to permit the air to pass from the intervening space to theinterior of the up per section.

The upper cylindrical portion of the upper section is located insubstantially the vertical plane of the walls of the base and it isprovided at opposite sides with recesses 14 in which are arranged theterminal portions 15 and 16 of a transversely disposed pipe 17 which hasa depressed intermediate portion formed by downwardly extending bends18. The end 15 of the transverse pipe 17 has an imperforate end wall orclosure 19 of any desired construction. The other end 16 is connected bya vertical pipe or branch portion 20 with a top transversely disposedgenerating pipe 21 located above and in spaced-relation with the lowertransverse pipe 17 connected with the vertical portion 22 of the supplypipe. The lower transverse pipe is preferably rectangular or oblong incross section while, the top transverse pipe is preferably circular incross section and the latter is equipped with a retort-23 which islocated directly above a nipple 2% extending upwardly from the center ofthe depressed portion of the lower transverse pipe 17.

The retort is preferably in the form of a cylindrical. casing providedat opposite sides with openings 25 to receive the top transverse pipe2lwhich is composed of two sections spaced apart to receive thecasing'between them. The cylindrical casing which has a top plate 28- isprovided with a series of spaced baffle plates 26 adapted to cause theliquid or gaseous fuel to travel back and forth across the cylindricalcasing of the retort before passing to the nipple 24:. The top plate 23is secured by screws or other suitable fastening devices to the bodyportion of the cylindrical casing. The lower portion of the uppersection of the burner proper constitutes a starting cup and a quantityof liquid hydrocarbon is placed in the lower imperforate portion of theupper section and is ignited causing the flame to impinge against thebottom pipe and also the top transverse pipe and heating the top-andbottom pipes sufliciently to generate gas from oil fed to the pipes. Theoil in passing through the upper generating. pipe is converted into agas and the gas ,passes downwardly through the connecting pipe 20 and isdischarged through the nipple where it burns beneath the retort.

The oil burners may be constructed of any suitable material and of anydesired size to adapt them for the particular heating apparatus in whichthey are to be used and it will be clear that owing to the relativelysmall bore of the nipple that the. gas gen erated in the pipes will bedischarged under pressure and a constant supply of gas maintained. Thelugs or legs 2 support the air inlet openings 12 above the grate orother supporting surface upon which the oil burner is placed and aproper supply of air to the interior or chamber of the inner casing orsection d is maintained both in the initial starting of the heater andin the operation of the same after the generation of gas in the pipe iscomplete. While it is preferable to use coal oil as a fuel a heavier oilmay of course be employed.

Vhat we claim is 1. A burner of the class described including a burnerproper composed of a base, and

bottom thereof and spaced therefrom between the top and bottom of thesaid base to form an intervening space, said base being provided at thebottom of the intervening space with an air inlet and the said uppersection having an air outlet communicating with the said base, saidupper section being closed at the bottom to form a starting cup, and apipeextending across the upper section and provided at an intermediatepoint with a discharge aperture.

2.
